Hi Guys,

Thanks for the replies.

I wanted to do the way I described, cause that way the user could use any tool available to him. But, as it turns out, this seems undoable. I ended up creating my own line tool that would do what I wanted.

Hi guys,

I need to do a plugin that will be used to outline windows and doors in a matched photo. The idea is that the user click a button before starting the outlining, draw some rectangles and when he is finished, he clicks in the button again.

It looks like a simple thing to do: When the user clicks the button for the first time, I add an EntitiesObserver and add all "onElementsAdded" to an array. When he clicks the button again, I loop through the array and do what I have to do (in my case, simply putting this entities in the deserved layer).

The plugin works as expected when I create rectangles within a surface. The problem is when one of the edges of the rectangle touches one of the edges of a previous modeled object. Sketchup triggers the element added with the face of the previous modeled object.

I know it maybe hard to understand the problem, but I'm leaving instructions on how to reproduce in the end of the post.

I wonder if you guys have any ideas on what I could do.

Thanks!

To reproduce the error:

1. Put the "bug.rb" file (uploaded here) in the plugin directory;
2. Create a simple box;
3. Click on plugin -> Start outlining window;
4. Within a face of the box, draw a square, without touching any of the edges of the box;
5. Click again on plugin -> Start outlining window;
6. Take a look in the layers (activating the "Color by layer" helps a lot). The new square should be in the "Window" layer;
7. Now, on another face of the box, redo step 3 to 5, but this time draw a rectangle and the bottom of the rectangle being drawn should touch the bottom of the box;
8. Check the layers again, and the box's face should have gone to the window layer, while the window is in the main layer (sometimes it works though @_@);
